Abstract
The present invention relates to a manual brake applied to a mine winch, which can be used on a conveying winch, a transporting winch, a dispatching winch, a prop-pulling winch and a low-speed winch. The manual brake a mine winch can be singly used, and a plurality of brakes can be simultaneously used on the same winch. The manual brake comprises a handle device which transfers the acting force amplified by two stages of manual force to a brake disk, and the small manual force is converted into the large braking force through the principle of Euler friction transmission. The manual brake applied to a mine winch has the characteristics of simple structure, large braking force, flexible and convenient operation, etc.
